GALVESTON, TX — The mother of Jayden
Lopez, a 4-year-old Houston boy recently identified after being found on a
Galveston beach last year in October, has been arrested, according to reports.
Lopez was known as "Little Jacob" until authorities were able to
identify him.

Rebecca
Rivera, 34, and her 31-year-old girlfriend Dania Gomez, were responsible for
Jayden's care when he died, Galveston Police Chief Vernon Hale said,
Click2Houston reports. The boy's autopsy suggests that he was dead before his
body was put into the water, where police believe was for 12 hours to two days.

"It is believed that both of
them were present when he was dead, and that both of them came to Galveston and
dumped his body," Hale said.

Bryan
Gaines of the FBI said nobody reported Jayden missing and that nobody was
looking for him. "Jayden has no advocate other than us," Gaines said,
Click2Houston reports.

Both Rivera and Gomez are being held
at the Galveston County Jail on bonds of $250,000 to $100,000, respectively.
